storing/retrieving image to/from database problems

[fadzizo abdullah]

Hi guys…

I’ve developed a midlet to store captured image from the phone’s camera into a database located on a server. At the server side, servlet is used to accept the captured image from the midlet and store in into the database.

The problem is, when I tried to retrieve the captured image and view it back on my midlet, half of the image became black except only small portion of the upper part of the image was ok.

Here are the code segments:


Midlet codes:

class FormAduan extends Form implements CommandListener{	
:
DBAS dbas;
private Player mPlayer;
private VideoControl mVideoControl;
private byte[] img;	
:

public byte[] getImg()
{
	return img;
}

public void capture()
{
	// Get the image.
	img = mVideoControl.getSnapshot(null);
}
}

class DBAS implements Runnable{
:
FormAduan faduan;
:

public void run()
{
		HttpConnection http = null;
		DataOutputStream os = null;
		DataInputStream in = null;
		String url = null;
		String message = null;

		if(cmd.equals("send"))
		{
			url = "http://192.168.1.9:80/servlet/AduanServlet";
			http = (HttpConnection)Connector.open(url);
			http.setRequestProperty("User-Agent","Profile/MIDP-2.0,Configuration/CLDC-1.1");
			http.setRequestProperty("Content Language","en-US");
			http.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
			http.setRequestMethod(HttpConnection.POST);

			os = (DataOutputStream)http.openDataOutputStream();
			os.write(faduan.getImg());
			os.flush();
		}
}
}
    

Servlet codes:

  
public void doPost(HttpServletRequest req, HttpServletResponse res)throws ServletException
{
	res.setContentType("text/plain");
	:
	DataInputStream in = new DataInputStream((InputStream)req.getInputStream());

	:

byte[] img = new byte[12288];
	in.readFully(img);

	Connection con = null;
	Statement st = null;
	ResultSet rs = null;
	Statement st2 = null;
	ResultSet rs2 = null;

	String url = "jdbc:mysql://localhost:3306/mAduan";

	Class.forName("com.mysql.jdbc.Driver").newInstance();
	con = DriverManager.getConnection(url, "root", "aku113");

	st = con.createStatement();

	PreparedStatement pst = con.prepareStatement("insert into aduan(adupic) values(?)");
	pst.setBytes(1,img);
int i = pst.executeUpdate();

	:
	rs.close();
}
  

I hope you guys can help and guide me….thanks in advance

Hi,

You need to set below lines in your code and then try..

http.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Configuration/CLDC-1.0");
http.setRequestProperty("Accept","text/html, image/gif, image/jpeg, image/");
